PRIMARY BIODIVERSITY DATA: Standardized plant observations from specimens, plots, & traits

BIEN – THE BOTANICAL INFORMATION AND ECOLOGY NETWORK – Plots, Specimens, and Traits:  The BIEN working group’s central goal –  To integrate the worlds botanical data to deliver (i) data integration tools; (ii) standardized botanical observation records, (iii) geographic range maps for all species in the New World and diversity maps, (iv)  species lists; and (v) a species-level phylogeny for all of the plants in the New World.  This information will enable us to better understand the determinants of the past and present plant diversity, distributions and abundance. This knowledge is essential for predicting how species, vegetation and agricultural crops will respond to future climate changes as well as providing a more accurate baseline to describe many dimensions of plant diversity (taxonomic, functional, and phylogenetic) in the New World. The BIEN database provides a common schema for merging georeferenced observations of individuals and species from specimens, vegetation inventories, and regional checklists, with measurements of species-level traits such as size, growth form, wood density, specific leaf area, etc. Currently these primary data are available only to members of the BIEN working group. However, our goal is to make available via this website any data whose owner is willing to make public access. We are currently working on securing distribution permissions. Derived products such as species niche models and range maps will also be made publicly available through the BIEN website.

SALVIAS – THE SALVIAS VEGETATION INVENTORY DATABASE – The SALVIAS vegetation inventory database (; GIVD ID 00-00-003) is a compilation of 13,661 vegetation inventories from around the world, with emphasis on the Americas. 12,962 inventories from the USA are shared with VegBank (; the remaining 699 inventories are mostly tropical forest plots from Mexico and Central and South America, and are available only via SALVIAS. The majority of the plots unique to SALVIAS contain individual measurements of trees, shrubs, lianas and hemiepiphytes, rather than aggregate observations (counts or percent cover). The two most common methods represented are 0.1 ha transects with a minimum stem diameter of 2.5 cm (523 plots) and 1 ha tree plots with a minimum stem diameter of 10 cm dbh (63 plots). The SALVIAS database also contains a taxonomically-standardized version of the Alwyn Gentry Forest Transects, also available in its original form for the Missouri Botanical Gardens website .

PLANT ALLOMETRY DATA BIOMASS ALLOCATION, ALLOMETRY, GROWTH DATA OF SEEDED PLANTS – This data set of leaf, stem, and root biomass for various plant taxa was compiled from the primary literature of the 20th century with a significant portion derived from Cannell (1982). This is a unique data set with which to evaluate allometric patterns of standing biomass within and across the broad spectrum of vascular plant species. Despite its importance to ecology, global climate research, and evolutionary and ecological theory, the general principles underlying how plant metabolic production is allocated to above- and below-ground biomass remain unclear. The resulting uncertainty severely limits the accuracy of models for many ecologically and evolutionarily important phenomena across taxonomically diverse communities. Thus, although quantitative assessments of biomass allocation patterns are central to biology, theoretical or empirical assessments of these patterns remain contentious. Data tables from Cannell (1982) are provided as companion documents.

The worlds trait data need to be free . . . the lab offers many differing plant functional trait databases and repositories and we are working to release and make available as much as possible.

  • BIEN – THE BOTANICAL INFORMATION AND ECOLOGY NETWORK – TRAITS – currently the BIEN network contains plant trait data from multiple literature sources, our respective research groups, and publicly available trait databases. In total,  34 plant functional traits consisting of 296,958 separate botanical observations. A total of 52,363 species within BIEN2 have at least one recorded trait value. Our trait data collection focused on trying to compile twelve core traits ( including the specific leaf area, the quotient of wet leaf area and dry leaf mass, seed size, wood density, and leaf stoichiometry), as these traits have been highlighted in the literature as critical traits linking plant growth, survivorship, and reproduction (Westoby 1998; Wright et al. 2004a). These traits were also intensively informed with a minimum of 4,000 species per trait. The BIEN3 update will greatly expand the coverage of trait data. We are working with iPlant and TRY to formally release these data. However, you can request access and read more about BIEN and data access here.

NSF MACROSYSTEMS DATA: Standardized tree, invertebrate, and soil microbial data across latitude

MACROSYSTEMS DATA – PLOT NETWORK OF STANDARDIZED TREE, FOREST, AND PLOT MEASURES ACROSS LATITUDE – A combination of standardized surveys in the field and controlled experiments in the field and laboratory measure diversity of three taxa — trees, invertebrates, and microbes — and key biogeochemical processes of decomposition in six forests distributed along a geographic gradient of increasing temperature from cold temperate to warm tropical. This ambitious, multi-pronged, highly integrated program of theoretical and empirical research takes advantage of the special expertise at the three collaborating institutions — James H. Brown and Bob Waide University of New Mexico, Brian J. Enquist, University of Arizona, Mike Kaspari and Joe Zhou University of Oklahoma. Currently we are archiving intra annual and annual measures of all trees within 35 standard 0.1 Gentry plots with annual and intrannual measures of tree size, growth, and mortality along with associated plant functional trait data and local climate within the LTER data repository via


  • STANDARDIZED GLOBAL TERRESTRIAL ECOSYSTEM WOODY PLANT NET PRIMARY  PRODUCTIVITY DATASETWoody plant biomass and production data comprising both above- and belowground components were compiled from multiple data sources including: (i) the Cannell data set that summarizes data from over 1,200 stands in 46 countries. (ii) the Luo  data set comprising data from over 5,000 forest stands across broad climate gradients in China; and (iii) we examined the primary references in recent publications and online data compilations and included data from 41 additional sites. Together, the compiled sites span most of the climate space in a plot of mean annual precipitation versus mean annual temperature. In addition, each site has detailed associated climate data as well as soil fertility information. This is the largest standardized global dataset for woody plant NPP for both above and below ground components.
  • WHOLE PLANT COMMUNITY BIOMASS, NPP, NUTRIENT DATASET – Whole community phytomass, nutrient, and productivity data from Kerkhoff et al. (2005).  Dataset consists of compiled data on standing phytomass, NPP and vegetation nutrient (N and/or P) content of whole plant communities from published sources. The communities span a variety of environmental conditions and functional types, from arctic tundra to tropical forests. Nutrient data were combined for all living vegetative components (i.e. roots, shoots and leaves, but not litter or reproductive organs) and divided by the total vegetation biomass to find whole-system nutrient concentrations.
